BACKGROUND Field

The present invention relates generally to structures for housing dataprocessing equipment, and, in particular, to data processing equipmentstructures that provide enhanced airflow solutions.

Background

Racks, frames and enclosures for mounting and storing computer and otherelectronic components or equipment have been well known for many years.Racks and frames are typically simple rectangular frameworks on whichelectronic components may be mounted, or on which other mountingmembers, such as shelves or brackets, may be mounted which in turn maysupport the electronic components. Enclosures are typically frames onwhich panels or doors, or both, are hung to provide aestheticimprovement, to protect the components from external influences, toprovide security for the components stored inside, or for other reasons.

Racks, frames and enclosures have been built in many different sizes andwith many different proportions in order to best accommodate thecomponents which they are designed to support and store. Componentsstored in these enclosures may include audio and video equipment and thelike, but quite frequently include computer equipment and relatedperipheral devices. These components typically include housingsenclosing internal operative elements.

As is also well known, the electronic equipment mounted in thesestructures tends to generate large amounts of thermal energy that needsto be exhausted away from the equipment effectively in order to maintainthe equipment in proper operating order or to prevent damage thereto.The problem can be especially significant when the components areenclosed in enclosures, because thermal energy generated thereby canconcentrate within the equipment enclosure and cause the components tooverheat and shut down. As equipment becomes more densely packed withelectronics, the quantities of thermal energy have continued to increasein recent years, and thermal energy management has become a significantissue confronting today's rack, enclosure, frame and enclosuremanufacturers, the manufacturers of the electronic equipment, and theusers of such equipment.

Typically, multiple racks, frames, enclosures, and the like (sometimescollectively referred to hereinafter as “enclosures”) are housedtogether in a data center room. Because of the overheating problem, andparticularly with multiple enclosures being placed in a single room,thermal management of the data center room is very important. A goal ofdata center thermal management is to maximize the performance, uptimeand life expectancy of the active components being housed in the room.Toward this end, data center rooms are often arranged so as to increaseefficiency and optimize performance.

One common way of organizing a data center room to meet these objectivesinvolves arranging individual enclosures in rows, with the air intake ofeach enclosure facing toward one side of the row and the heated airexhaust of each enclosure facing toward the other side of the row. Rowsof enclosures are arranged in back-to-back relationship so thatenclosures of two separate rows exhaust heated air into a common “hot”aisle between the rows. Heated exhaust air from the hot aisle is thendrawn into a cooling unit—often arranged as an in-line unit within therow of enclosures. The cooled air is then deposited back into theambient space of the data center room to be re-used in the coolingprocess.

In such an arrangement, however, several drawbacks are known to exist.For instance, the establishment of a hot aisle between rows eliminatesthe possibility of having dedicated cooling units to manage the coolingprocess for each row individually. Additionally, under existing hotaisle methodology, the entire space of the data center room must be keptcool in order to provide a ready supply of cooled air available to theenclosure intakes. Due to its typically large volume, the data centerroom is generally incapable of being adequately pressurized.

Accordingly, a need exists for improvement in the arrangement ofequipment enclosures within a data center room so as to further enhanceefficiency and performance. This, and other needs, is addressed by oneor more aspects of the present invention.

As a preliminary matter, it will readily be understood by one havingordinary skill in the relevant art (“Ordinary Artisan”) that the presentinvention has broad utility and application. Furthermore, any embodimentdiscussed and identified as being “preferred” is considered to be partof a best mode contemplated for carrying out the present invention.Other embodiments also may be discussed for additional illustrativepurposes in providing a full and enabling disclosure of the presentinvention. Moreover, many embodiments, such as adaptations, variations,modifications, and equivalent arrangements, will be implicitly disclosedby the embodiments described herein and fall within the scope of thepresent invention.

Accordingly, while the present invention is described herein in detailin relation to one or more embodiments, it is to be understood that thisdisclosure is illustrative and exemplary of the present invention, andis made merely for the purposes of providing a full and enablingdisclosure of the present invention. The detailed disclosure herein ofone or more embodiments is not intended, nor is to be construed, tolimit the scope of patent protection afforded the present invention,which scope is to be defined by the claims and the equivalents thereof.It is not intended that the scope of patent protection afforded thepresent invention be defined by reading into any claim a limitationfound herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps ofvarious processes or methods that are described herein are illustrativeand not restrictive. Accordingly, it should be understood that, althoughsteps of various processes or methods may be shown and described asbeing in a sequence or temporal order, the steps of any such processesor methods are not limited to being carried out in any particularsequence or order, absent an indication otherwise. Indeed, the steps insuch processes or methods generally may be carried out in variousdifferent sequences and orders while still falling within the scope ofthe present invention. Accordingly, it is intended that the scope ofpatent protection afforded the present invention is to be defined by theappended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refersto that which the Ordinary Artisan would understand such term to meanbased on the contextual use of such term herein. To the extent that themeaning of a term used herein—as understood by the Ordinary Artisanbased on the contextual use of such term—differs in any way from anyparticular dictionary definition of such term, it is intended that themeaning of the term as understood by the Ordinary Artisan shouldprevail.

Furthermore, it is important to note that, as used herein, “a” and “an”each generally denotes “at least one,” but does not exclude a pluralityunless the contextual use dictates otherwise. Thus, reference to “apicnic basket having an apple” describes “a picnic basket having atleast one apple” as well as “a picnic basket having apples.” Incontrast, reference to “a picnic basket having a single apple” describes“a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one ofthe items,” but does not exclude a plurality of items of the list. Thus,reference to “a picnic basket having cheese or crackers” describes “apicnic basket having cheese without crackers,” “a picnic basket havingcrackers without cheese,” and “a picnic basket having both cheese andcrackers.” Finally, when used herein to join a list of items, “and”denotes “all of the items of the list.” Thus, reference to “a picnicbasket having cheese and crackers” describes “a picnic basket havingcheese, wherein the picnic basket further has crackers,” as well asdescribes “a picnic basket having crackers, wherein the picnic basketfurther has cheese.”

Referring now to the drawings, in which like numerals represent likecomponents throughout the several views, the preferred embodiments ofthe present invention are next described. The following description ofone or more preferred embodiment(s) is merely exemplary in nature and isin no way intended to limit the invention, its application, or uses.

FIG. 1 is a front orthogonal view of a data processing equipmentstructure 10, in accordance with one or more aspects of the presentinvention, shown with cooling units 14 disposed at ends of a row ofequipment enclosures 12. FIG. 2 is a front orthogonal view of a dataprocessing equipment structure 10, in accordance with one or moreaspects of the present invention, shown with cooling units 14 disposedat an end and intermediate of ends of a row of equipment enclosures 12.As used herein, the term “data processing equipment” refers to a widerange of electronic equipment as well as racks, frames, enclosures, andthe like that are typically used to house such equipment.

As shown in FIGS. 1 and 2, the data processing equipment structure 10generally includes sidewalls 22,24 and a ceiling panel 28. Together, thesidewalls 22,24 and ceiling panel 28 enclose a row of enclosures 12resting on a floor surface 40 in a data center room. In a preferredembodiment, the sidewalls 22,24 and ceiling panel 28 are solid so as toprevent mixing of air from outside the structure 10 with the controlledenvironment within. Although not a required feature, the structure 10may optionally include a floor panel 26 resting on or above the floorsurface 40 such that the row of enclosures 12 rests on the floor panel26. In FIGS. 1 and 2, the front sidewall 24 and ceiling panel 28 areshown as being transparent in order to illustrate the row of enclosures12 contained within the structure 10, while the other walls are shown asbeing opaque. In fact, any of the panels may be transparent or opaque asdesired.

As further shown in FIGS. 1 and 2, one or more in-line cooling units 14are arranged within the row of enclosures 12. In FIG. 1, a cooling unit14 is disposed at each of the two ends of the row of enclosures 12.However, there may also be a need to include a cooling unit 14intermediate of the ends of a row of enclosures 12, as shown in FIG. 2.While two cooling units 14 are depicted in each of FIGS. 1 and 2, moreor less cooling units 14 may be included, as might be appreciated by theOrdinary Artisan. Cooling units 14 are generally, though perhaps notalways, disposed proximate to enclosures 12 that house equipment in needof cooling. Because all enclosures 12 may not be in use at all times,the location of the cooling units 14 within the row can be matched withenclosures 12 that are in use. Enclosures 12 house a wide variety ofelectronic equipment, including storage equipment, servers, switches andother like devices and equipment for data processing. Cooling units 14embedded within the row may utilize a wide variety of cooling solutions,including DX cooling, chilled water cooling and other types ofeconomized cooling solutions.

FIGS. 3 and 4 are respective front and rear orthogonal views of the dataprocessing equipment structure 10 of FIG. 2, shown with circulationlines or arrows illustrating airflow. The front sidewall 24 and ceilingpanel 28 in FIG. 3 and the rear sidewall 24 and ceiling panel 28 in FIG.4 are shown as being transparent in order to illustrate the row ofenclosures 12 contained within the structure 10. FIG. 5 is a sectionalview of the data processing equipment structure of FIG. 2, taken alongline 5-5. As collectively shown therein, the structure 10 is divided orcompartmentalized to define a front plenum 50 at or along the front sideof the row of enclosures 12 and a rear plenum 60 at or along a rear sideof the row of enclosures 12. In the arrangement shown, the front plenum50 houses the cool air supply of the structure 10 provided by thecooling units 14 and is in fluid connection with the air intakes of thevarious enclosures 12, while the rear plenum 60 contains heated exhaustair exhausted from equipment mounted within the enclosures 12 and is influid connection with the air intakes of the cooling units 14. However,it will be appreciated that this arrangement may be reversed such thatthe rear plenum 60 houses the cool air supply and the front plenum 50contains the heated exhaust air.

The front plenum 50 and rear plenum 60 are separated from one another bythe enclosures 12 and the cooling units 14 in combination with one ormore separation panels 16,18. As perhaps best shown in FIG. 5,separation panels 16 extend from the tops of the air cooling units 14 tothe ceiling panel 28, and separation panels 18 extend from the tops ofthe enclosures 12 to the ceiling panel 28. Separation panels 16,18 thusensure that the cool air supply of the front plenum 50 is isolated fromthe heated exhaust air of the rear plenum 60.

As shown in FIG. 3, cool air (represented by arrows shown in outlineform) enters the front plenum 50 via the cooling units 14 and isdispersed within the front plenum 50. Separation panels 16,18 preventthe cool air in the front plenum 50 from mixing with the heated exhaustair in the rear plenum 60. Cool air is then drawn into the air intakesof the enclosures 12 to cool equipment mounted therein. Conveniently,the cooling units 14 may be arranged within the row at locationsproximate to enclosures 12 that house equipment to be cooled.

As shown in FIG. 4, heated exhaust air (represented by arrows shown insolid form) is exhausted from the rear sides of the enclosures 12 intothe rear plenum 60. Heated exhaust air is contained within the rearplenum 60, separate from both the front plenum 50 and any other rows ofelectronic equipment within the data center room. From the rear plenum60, heated exhaust air is drawn into the air intakes of the coolingunits 14 where it is cooled before being reintroduced into the frontplenum 50 as cooled air.

FIG. 6 is a front orthogonal view of a data processing equipmentstructure 10, in accordance with one or more aspects of the presentinvention, shown with an internal sidewall 30 to scale the size of theinternal space for housing equipment enclosures 12. In FIG. 6, the frontsidewall 24 and ceiling panel 28 are once again shown as beingtransparent in order to illustrate the row of enclosures 12 containedwithin the structure 10. As shown in FIG. 6, the structure 10 is capableof easy modification in order to suit the particular needs of a datacenter. More particularly, if only a few enclosures 12 are required fora particular data center, an internal sidewall 30 may be configuredwithin the structure 10 to isolate any unneeded space (i.e., the spaceat the rightmost end of the structure 10 of FIG. 6) from actively usedspace (i.e., the space at the leftmost end of the structure 10 of FIG.6) where electronic equipment is maintained. The internal sidewall 30may be located in any of a number of different positions within thestructure 10 so as to permit scaling the size of the structure 10 to apreferred size to accommodate more or less equipment enclosures 12. Assuch, the internal space of the structure 10 is capable of expansion orreduction in size to address particular needs of a data center.

In accordance with another aspect of the present invention, thestructure 10 may be configured to provide additional scalabilityfeatures. In particular, individual enclosures 12 within the row may befitted with active and passive louvers (not shown) such that eachindividual enclosure 12 may be rendered active or inactive within thestructure 10. Furthermore, it is also contemplated that individualenclosures 12 within the row may include solid caps (not shown) capableof being fitted to the front or rear of the respective enclosure 12,thereby covering the air intake or hot air exhaust of the respectiveenclosure 12. In this regard, individual enclosures 12 may be renderedinactive without the need of removing the enclosure from the structure10.

As shown in FIGS. 1-6, the structure 10 provides an environment forthermal management of a row of equipment enclosures 12. Where the datacenter room includes multiple rows of equipment enclosures, thermalmanagement of each individual row is possible in accordance with thepresent invention, as the supply of cool air in the front plenum 50 andheated exhaust air in the rear plenum 60 of a particular row can beeffectively isolated from other rows. Each individual row of equipmentenclosures 12 is capable of thermal management by one or more dedicatedcooling units 14 within the row. As such, what is often a very complexair space within a data center room can be simplified in a manner suchthat each row is capable of being managed independently of other rows.

By limiting the air interaction between separate rows of electronicequipment 12, the methodology of the present invention simplifiescontrol of the thermal management process. Cooling needs for eachindividual row can be ascertained, which facilitates the application ofsimple control algorithms to manage the process and maximize airflow andcooling efficiency of each row in the data center room. With enhancedairflow efficiency, cooling units can operate at a lower power state,thus enhancing power consumption of the structure 10 as well.

Separation of the front plenum 50 from the rear plenum 60 furtherenhances the energy efficiency of the structure 10 by reducing orminimizing wasted airflow arising from recirculation or bypass, whichcan ultimately increase the rate of heated air exhausted into the rearplenum 60 during the cooling process. Such an increase facilitates animprovement in the efficiency of cooling coils of the cooling units 14,which allows for a reduction in cooling unit fan speed. In this regard,a reduction in fan speed can reduce power consumption and therebyenhance the energy efficiency of the structure 10.

Energy efficiency of the structure 10 is also enhanced by the relativelyshort airflow path afforded by the structure 10. Cooling units 14 can belocated within the row to be proximate to enclosures 12 that houseelectronic equipment. By coupling cooling units 14 with enclosures 12,the airflow path can be direct and short, thus providing a ready supplyof cool air in the vicinity of the enclosure 12. Furthermore, as shownin FIGS. 1-6, the volume of the front plenum 50 is relatively small,which can facilitate a pressurized state. Such pressurization at thecool air intake of enclosures 12 can further enhance airflow throughelectronic equipment.

In accordance with various aspects of the present invention, power maybe provided to the cooling units 14 and electronic equipment mountedwithin the enclosures 12 by means of a busway. Power may also beprovided to the cooling units 14 and electronic equipment mounted withinthe enclosures 12 via conduit and junction boxes. In accordance withother aspects of the present invention, the structure 10 may be fittedwith various integrated systems, such as security systems, firesuppression systems, lighting systems and general IT managementoperation systems. In this regard, the structure 10 of the presentinvention is capable of managing a multitude of functions for anindividual row of enclosures 12, including thermal management, power,fire suppression and other critical functions.

It is further contemplated that multiple structures 10 can be organizedwithin a single data center room, with each separate structure 10 beingspecifically configured to enhance or optimize thermal management withrespect to equipment mounted therein.

FIG. 7 is an isometric view of a second embodiment of a data processingequipment structure 110 in accordance with one or more aspects of thepresent invention. As shown therein, the data processing equipmentstructure 110 generally includes a plurality of equipment enclosures 112organized in a row and at least one cooling unit 114. Although onecooling unit 114 is shown, it is contemplated that multiple coolingunits 114 may be implemented within the row. The cooling unit 114includes or operates in conjunction with a cooling fan 117 to assist infacilitating airflow during the cooling process. The structure 110further includes an overhead duct 115 (shown as being transparent inFIG. 7) for containing and directing air during the cooling process. Theoverhead duct 115 is in fluid communication with the enclosures 112 andthe cooling unit 114.

In accordance with this embodiment, airflow can be directed such thatcool air is drawn into the enclosures 112 from the environment in whichthe structure 110 is organized. Cool air is utilized to cool equipmentmounted in the enclosures 112 and is then exhausted into the overheadduct 115 as heated exhaust air. From the overhead duct 115, heatedexhaust air may be directed toward the in-line cooling unit 114 wherethe heated exhaust air is cooled before being reintroduced to the supplyof cool air outside of the structure 110.

Airflow can also be directed such that cool air is drawn into enclosures112 from the overhead duct 115. In this arrangement, cool air isutilized to cool equipment mounted in the enclosures 112 and is thenexhausted into the environment outside the structure 110 as heatedexhaust air. The in-line cooling unit 114 then draws heated exhaust airfrom the exterior environment to be cooled before being reintroduced tothe supply of cool air contained within the overhead duct 115.

FIG. 8 is an isometric view of a third embodiment of a data processingequipment structure 210 in accordance with one or more aspects of thepresent invention. As shown therein, the data processing equipmentstructure 210 generally includes a pair of rows of equipment enclosures212 that are arranged in side-to-side relationship. Together, the rowsof enclosures 212 define an aisle 219 therebetween. The structurefurther includes a cooling unit/fan 217 above the aisle and an overheadduct 215 (shown as being transparent in FIG. 8) for containing anddirecting air during the cooling process. The overhead duct 215 is influid communication with the enclosures 212 and the cooling unit/fan217. Although one cooling unit/fan 217 is shown, it is contemplated thatmultiple such units may be implemented above the aisle 219. It isfurther contemplated that one or more doors may be utilized to seal endsof the aisle 219 from the outside environment and provide access to theaisle 219 when necessary.

In accordance with this embodiment, airflow can be directed such thatcool air is drawn into enclosures 212 from the aisle 219 between therows.
